Basics

This module provides `argv` which handles command line arguments. For example,  ~$ python -c "import sys; print(sys.argv)" one 2 3rd  ['-c', 'one', '2', '3rd']  ~$     The command line arguments above were stored as follows:  ~$ python -c "import sys; print(sys.argv[0])" one 2 3rd  -c  ~$ python -c "import sys; print(sys.argv[1])" one 2 3rd  one  ~$ python -c "import sys; print(sys.argv[2])" one 2 3rd  2  ~$ python -c "import sys; print(sys.argv[3])" one 2 3rd  3rd  ~$     Other related modules are:  `getopt`   - processes sys.argv using Unix getopt() function
